Move the extracted JDK into the tool-cache and speed up extraction (#1206)

Browse Source 
Two wall-clock optimizations on the JDK install path.

`tc.cacheDir` recursively copies the extracted tree into RUNNER_TOOL_CACHE,
so a 200-600MB JDK is written to disk twice. The extraction directory and
the tool-cache normally share a filesystem, so `cacheJdkDir` renames it
instead and writes the `.complete` marker itself, mirroring the destination
layout `tc.cacheDir` produces. It falls back to the copy when the tool-cache
location is unknown, when the source is not a real directory (a symlinked
source would otherwise leave a dangling entry once RUNNER_TEMP is cleaned),
or when the rename fails - a cross-device tool-cache, or anti-virus holding
a handle on Windows. The rename is atomic, so the source is still intact
for the fallback.

Extraction now uses `pigz` for tarballs when the runner provides it, and
Windows zips go through the bundled `tar.exe` rather than `tc.extractZip`,
which shells out to PowerShell's much slower `Expand-Archive`. Both fall
back to the stock extraction and clean up the abandoned directory first.
